One brief investigative report on an unusual aspect of Texas law that allows prosecutors to withhold evidence from the defense before trial

This powerful six-minute report is a model of investigative reporting by a local station. It reveals a local loophole in one of the basic principles of American justice -- the right of defendants to all evidence against them before trial. Reporter Jeremy Rogalski details how the law in some Texas counties, unlike most places in the U.S., allows prosecutors to withhold pre-trial evidence from the defense. The story builds steadily, making a persuasive case about how damaging, uneven and unfair this common and perfectly legal practice is. The report reveals how prosecutors withhold evidence in police, eyewitness and lab reports, sometimes resulting in wrongful convictions and long prison terms.
